Changing HEPA filters
Replace the HEPA filter if suction power is still weak after replacing the
filter bag. The HEPA filter is located behind the filter bag.
NOTE
Nature and source of the danger
We recommend replacing the HEPA filter for the CEREC suction
device once the filter bag has been replaced around 3 to 4 times. This
number may differ depending on the amount of zirconium oxide
materials milled and suctioned.
1. Loosen the two knurled nuts (A) on the maintenance cover.
2. Remove the lid.
3. Remove the filter bag from the nozzle.
4. Then release and remove the two Phillips screws on the perforated
sheet on the inside of the suction system.
5. Take the perforated sheet out.
